CentOS7 installation Python-pip

One of the most useful package management tools in Python is Python-pip is an essential tool for our use of Python. But there are some minor problems with CentOS7 installation:

[[email protected] magic]# yum install Python-pip loaded plugin: fastestmirror, langpacksloading mirror speeds from cached hostfile * Base:mirrors.btte.net * extras:mirrors.btte.net * updates:mirrors.btte.net no available packages Python-pip. Error: No processing required

　　

After reviewing the information, it is because the official CentOS source some time lag caused. So we can use the EPEL (Http://fedoraproject.org/wiki/EPEL) built by the Fedora community to install:

Then install PYTHON-PIP:
